1 Claim. (Cl. 215-46) This invention relates to devices for removingconventional bottle caps of the type crimped over beads on the ends ofnecks of bottles, and in particular a comparatively small thin plateadapted to be crimped under the edge of a bottle cap and permanentlysecured in position thereby, and said plate having a thumb nail grippingportion by which the plate is pulled outwardly to pry the cap from thebottle extending downwardly therefrom and nested against the outersurface of the neck of the bottle.

The purpose of this invention is to provide means for removing bottlecaps wherein the removing means is supplied with each bottle so that thenecessity of looking or hunting for a bottle cap remover or opener isobviated.

The conventional bottle cap, used primarily, for soft drinks, beer, andthe like is crimped over a bead at the end of the neck of the bottle anda gasket secured to the inner surface of the cap provides a seal wherebythe bottle is sealed until the cap is removed. With the conventional capremover or bottle opener a prong or end section bears downwardly againstthe center of the cap as a prong or blade grips the edge of the crimpedportion of the cap whereby the edge of the cap is bent upwardly breakingthe seal and thereby making it possible to remove the cap. With suchdevices it is necessary to provide bottle openers in refrigeratingcabinets for soft drinks and when cartons of bottles are carried toremote points, such as on picnics, conventional bottle openers are oftenoverlooked and it i often difiicult to open bottles. With this thoughtin mind this invention contemplates a bottle opener that is permanentlyinstalled under a bottle cap whereby the opener is in positioncontinuously so that bottles may be opened even though conventionalbottle openers are not available.

The object of this invention is, therefore, to provide means for forminga bottle opener whereby an opener may be crimped under a bottle cap sothat it remains in position until used.

Another object of the invention is to provide a bottle opener adapted tobe permanently attached to a bottle in which the opener nests againstthe outer surface of the neck of the bottle so that its presence on thebottle is not objectionable.

A further object of the invention is to provide a bottle opener of thepermanently attached type in which the opener is of a simple andeconomical construction so that it may be discarded after use.

With these and other objects and advantages in view the inventionembodies a comparatively small plate having arcuate sections and havingtapering edges converging from a flange at the top substantially to apoint at the lower end wherein the flange at the top is formed to beinserted under the edge of a bottle cap with the body of the devicenested against the outer surface of a bottle.

Other features and advantages of the invention will appear from thefollowing description taken in connection with the drawing, wherein:

2,781,142 F'atented Feb. 12, 1951 Figure 1 is a vertical section throughthe upper endof the neck of a bottle showing the improved bottle openernested against the outer surface of the neck and with a flange at theupper end of the opener crimped under the edge of the bottle cap.

Figure 2 is a detail showing a perspective view of the improved bottleopener.

Figure 3 is a front elevational view of the opener.

Figure 4 is a plan view of the opener showing the opener positionedagainst the outer surface of a bottle, the bottle being shown in brokenlines.

Figure 5 is a side elevational View showing the upper end of the neck ofa bottle with a cap positioned thereon and illustrating the position ofthe bottle opener on the bottle with the upper end crimped under the capand also showing the manner of gripping the opener with a thumb nail topry the opener outwardly for removing the cap.

Figure 6 is a similar view showing the bottle cap partly removed.

Referring now to the drawing wherein like reference characters denotecorresponding parts the improved bottle opener of this invention includea plate 10 having a flange 11 with an arcuate recess 12 in theintermediate portion, formed on the upper end and having tapering edges13 and 14 generally converging from the flange toward an arcuate section15 at the lower end.

The plate is formed with a transversely disposed recess 16 that nests inan annular recess 17 below a bead 18 on the upper surface of a neck 19of a bottle and from the recess 16 the lower portion of the plate bulgesoutwardly to correspond with the outer surface of an annular bulge 29 onthe surface of the neck of the bottle. The plate, however, may bepatterned to correspond with outer surfaces of bottles of difierentshapes.

The flange 11 of the upper end of the plate is also formed to correspondwith the outer surface of the bead 18 and, as illustrated in Fig. 1 thedevice is installed as a cap, such as the cap 21 is crimped over thebead 18 at the upper end of the neck of a bottle, the flange 11 beingpositioned inside of the crimped edge of the cap. The cap is providedwith the conventional sealing washer or gasket 22.

By this means the improved bottle opener of this invention remains inposition continuously and when it is desired to open the bottle thelower tip of the device is gripped, such as by a thumb nail as shown inFig. 5 and drawn outwardly, as illustrated in Fig. 6 whereby the edge ofthe cap is pried outwardly to break the seal so that the cap may beremoved.

t will be understood that modifications, within the scope of theappended claim, may be made in the design and arrangement of the partswithout departing from the spirit of the invention.

What is claimed is:

As a new article of manufacture, a container cap remover for use with acontainer of the type having a neck provided with an annular head on itsupper end, there being an annular bulge below said bead on the neck ofthe container, there being an annular recess between said bulge andbead, a cap mounted on the top of said container and having a portioncrimped over the bead on said neck, said cap remover being fabricated ofa single piece of material and shaped to include a plate having a flangeon its upper end, said flange being interposed between the crimpedportion of said cap and said head, said flange being smooth on both itsinner and outer surfaces, there being an arcuate recess in said flangeintermediate the ends thereof, said recess extending downwardly from theupper edge thereof, said plate further including a central curvedportion fitting snugly against said bulge and the side edges of saidcentral portion tapering inwardly, said plate being provided with atransversely disposed recess snugly seated in the recess between saidbead and bulge, the recess in said plate receiving a portion of thecrimped section of the cap,:s'aid plate further including an arcuatesection at its lower end positioned below said bulge for engagement byepersons fingers, said cantepiover adapted to be mounted on the containelwithout altering the shape or stl ucture of the container, said platecontacting approximately one fourth of the circumference of the neek'ofthe container throughout the length of the plate, said flange having awidth approximately equal to the width of the central curved portion atthe Widest point of the central curved portion.
